APPARATUS FOR MAKING SERRA'IED ROOFING-STRIPS.

Specification of Letters-Patent.

Pat'ented'MaIchB, 1908.

Application filedMarchltZ, 1907. .Serial No. 362,986.

To all whom it may concern;

Be it known that I, FREDERICK G. OVER BURY, of N ewYork, in the county of New York and State ofNew York, have invented certain new and useful Improvements in Apparatus for Making Serrated Roofing-Strips, of which the following is a s ecification.

This invention relates to e lOngated roofing strips of flexible water-proof material adapted to be laid on roofs and walls' of buildings, each strip having a serrated edge adapted to be laid in such manner as to give the effect of a roof or wall covered with pointed shingles, the projections of one serrated edge alternating with the projections forming the serrated edge of the next strip below it, in .the man-' ner illustrated in my application for Letters Patent of the United States, Serial No. 318,903, filed May 26, 1906.

The invention has'for its object to provide means for rapidly and economically forming serrated roofing strips and. for winding or packaging the same in such manner as to form a compact rollor package including a plurality-of serrated strips, the serrations of each strip being interlocked with the serrations ofanother strip, so that the projections of each serratededge are guarded and protected by the projections of an adjoining serrated strip.

The invention consists in the improved apparatus which I will now proceed to describe and claim. p

Of the accompanying drawings, forming a part of this specification,Figure 1 represents a side view of an apparatus embodying my invention. Fig'. 2- represents atop plan view of the same. Fig. 3 represents a erspective view of a partially formed rol or package of roofing material produced by the apparatus shown in Figs. 1 and 2. Fig. 4 represents a top plan view of a' ortion of the apparatus, shown in Figs. 1 an 2, representing a somewhat different embodiment ofthe invention. Fig. 5 represents a side elevation of a different form of zigzag cutter.

The same letters of reference indicate the same parts in all the figures.

In the drawings, 2 represents a roll or mandrel j ournaled in bearings, supported by standards 8, the said mandrel being adapted to support a sheet4 of suitable flexible waterproof roofing materialwound in a roll upon naled in bearings in suitable standards or housings 7,-adjacent to the standards-suporting the mandrel 2: Thelower roll 5..is -.a bed roll, and the upper roll 6 is a outterroll provided with a continuous zig-zag cutter 8, which is supported by a bed roll and is adapted to form a'zig-zag longitudinal cut 9 vin-a sheet 4 passed between the rolls, suitable means being provided toexert pressure. on the roll 6 and its cutters su'flicient tocause the cutters to pass through the. thickness of the sheet and sever it into two strips 1010, each having a serrated edge.

. 12 represents a winding reel or mandrel, journaled in suitable .standards 13, and adapted to'wind thestrips 1 0 *10into.;.a: roll or, package 14 (Fig. 3).

15 represents a bed or table located .between the pair. of rolls 5 and -6 .and the winding reel 12, the said bed being adapted to support the subdivided portion of the sheet passing from the said rolls to the reel and prevent the subdivisions from separating from each otherafter they leave the cutter, the result being that the serrations of the strips 10' 10. arrive at the reel 12 and are added to the convolutions of the roll thereon without sidewise displacement relatively'to each other, the projections of each serrated edge 9 remaining in interlocked engagement with the projections of the other strip 10, so that the two strips are wound as one sheet upon the reelor mandrel 12. Without some means, such as afforded by the bed or table 15, to prevent the projections from sagging with the projections interlocked. A com edges forming the original margins of the sheet, while the serrations point inwardly -from the ends of the roll andare interlocked with each other and thus protected so that they cannot be displaced or broken while The strips are readily separable from each other when unrolled, each package being composed of a plurality of readily divisible serrated strips.

have used the term zig-za'g in characterizing the-cutter 8. I desire it to be understood, however, that I do not mean by this term to limit myself to 'anangular cutter formed to produce the an .l-ar s er- 'loosely after being cut, there could be no certainty of the roll being formed smoothly pact roll or package is thus formed, the ends of which are formed by the straight outer the roller package is in transit or storage.

; r ations shown in Figs. -2 and 3fl The cutter maybe curved so as to produce a serrated edge made up of curved projectlons and recesses, or the projections and recesses may 5 have any other'desired form.

InFig. 4, I show the, cutter roll 6 provided with two zig-za cutters 8 adapted to form two longitudina "zig-zag cuts ;1n the sheet, and an intermediate circular cutter 16 ada ted to form a straight longitudinal cut 17 1 etween the said'zig-zag cuts, revision being thus made for converting t e sheetinto four strips, each having a serrated edge and a straight edge.

'-I claim 1 1. An apparatus of the character stated,

comprisin' means for supporting a rolled.

sheet of exibleroofing material, a reel to which the said sheet is transferable by the rotawhich thesheet passes, said' r0l1s comprising a bed roll ada ted to support the-sheet, and

a cutter r'oll. aving a zig-zag cutter sup-o ported by the bed roll and adapted to form means for holding the injections in the same plane'and interloc edafter they are cut.

2. An apparatus tion of-the reel, intermediate rolls between a longitudinal 'zig-zag cut in the, sheet, and

of the character stated,

comprising means for supporting a rolled sheet of flexible roofing material, a reel to k which the said sheet is transferable by the 'rotation of the reel, intermediate rolls between which the sheet passes, said rolls comprising abed roll ada ted to support the --sheet, and a cutter roll aving a zig-zag cutter supported bythe bed roll and adapted to "form a ongitudinal zig-zag cut in the sheet,

and a bed or table interposed between the said rolls and the reel, and adapted to support the subdivided portion of the sheet.

, '3. In an apparatus of the character stated, v

I a ted to support a strip of flexible materia traveling over it, a cutter roll having a plurality of zig-zag cutters adapted to form a lurality of longitudinal zig-zag cuts inlthe s eet, means for formin a straight longitudinal out between the sai zig-zag cuts, a' winding reel for the cut-strip, I and means for'holding the cut edges offthe pass from
